• Introduction and Background on BC’s Organic Matter Recycling Regulation (OMRR)

• Implementation of OMRR

Organic Matter Recycling RegulationOrganic Matter Recycling Regulation

• Enacted February, 2002

• Replaced BC Composting Regulation and Biosolids Permit System

• Based on research; developed over 6 years with many stakeholders

• Authorized under both the Environmental Management Act and Health Act


Waste Management Act and Health Act• A discharger must, …., give notification of any ….

land application of managed organic matter in volumes greater than 5 cubic metres to:

• the manager ….. before the land application of managed organic matter;

• the medical health officer …… before the land application of managed organic matter to agricultural land or in a watershed;

• the Land Reserve Commission ….before the land application of managed organic matter within an agricultural land reserve or forest reserve land.

Organic Matter RecyclingOrganic Matter Recycling

• The manager may …. request additional information.

• The manager may ….. require the discharger to meet the site-specific standards or management practices specified by the manager.

Organic Matter RecyclingOrganic Matter Recycling

• The medical health officer …. may…… provide written directions to the discharger that the application of managed organic matter

• must not proceed, or

• may only proceed subject to conditions specified by the medical health officer.
